Therefore, their accurate identification facilitates their use in the improvement of these crops. Based on chloroplast DNA analysis (rpL2 and rps16 introns, psbC-trnS, trnT-L, and trnL-F) using polymerase chain reaction (PCR) and PCR-restriction fragment length polymorphism (PCR-RFLP), an attempt was made in 2018 (Department of Molecular Biology and Biotechnology/AECS) to identify durum and bread wheats from each of their proposed diploid ancestral species (i.e., T. monococcum, T. urartu, Aegilops speltoides, and Ae. tauschii). The use of two PCR markers (psbC-trnS and trnL-F) and three PCR-RFLP locus-enzyme combinations (rps16 intron-Tru 1I, rpL2 intron-Taq I, and trnT-L-Taq I) allowed the identification of all species involved. Reliable and accurate identification of diploid ancestors of durum and bread wheats using these candidate species-specific cpDNA markers will be useful for wheat breeding programs, in situ and ex situ conservation efforts, verification of seed purity in commercial seed stocks, and ensuring identity and integrity of accessions held within a collection does not change through unwanted gene flow or by genetic drift after regeneration by seed.","PeriodicalId":7527,"journal":{"name":"Agriculture (Pol'nohospodárstvo)","volume":"45 1","pages":"56 - 66"},"PeriodicalIF":0.0,"publicationDate":"2020-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74082199","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For this reason, fertiliser manufacturers are working to create products that combine biochar with other soil fertility enhancers suitable for different soil-climatic conditions. In this study, two types of biochar substrates (1. biochar blended with farmyard manure, and 2. biochar blended with farmyard manure as well as with digestate) at rates of 10 and 20 t/ha were applied alone or in combination with other manure and mineral fertilisers. These were added to Arenosol (sandy soil, Dolná Streda, Slovakia) and Chernozem (loamy soil, Veľké Úľany, Slovakia) to evaluate the soil physical properties to test the potential of these amendments for soil amelioration in texturally different soils. The results showed that the application of biochar substrates alone increased soil moisture, the volume of capillary pores, and decreased aeration and volume of non-capillary pores. The application of biochar substrates with mineral fertilisers increased aeration, content of water-stable macro-aggregates (WSAma), total porosity, and decreased soil moisture and the content of water-stable micro-aggregates (WSAmi) in sandy soil. In loamy soil, when compared to unfertilised control, the biochar treatments increased content of WSAma, content of dry-sieved macro-aggregates, and decreased content of WSAmi and content of dry-sieved micro-aggregates. The combination of biochar substrates together with manure had no effect on changes in the physical properties of loamy soil.","PeriodicalId":7527,"journal":{"name":"Agriculture (Pol'nohospodárstvo)","volume":"25 1","pages":"45 - 55"},"PeriodicalIF":0.0,"publicationDate":"2020-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84370537","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Electrical geophysical methods (i.e. vertical electrical resistivity sounding) allow performing rapid measurement of soil electrical properties directly from the soil surface to any depth without any mechanical disturbance of soil cover. Soil electrical properties are linked with many soil properties and could improve the quality and spatial coverage of soil surveys. The results obtained in our study using vertical electrical resistivity sounding confirmed the hypothesis of a high correlation between electrical resistivity and such soil properties as carbon and nitrogen content and silt content. The highest correlation (r > 0.9) was found for electrical resistivity and carbon content. It was also confirmed that significant correlations between electrical resistivity and soil properties are found mainly when soil properties are highly ranged. Perspectives for the applied method lie at the relationship between electrical resistivity and soil properties, such as texture class, clay content, carbon content, and cation exchange capacity. The results obtained in this work could be useful for complex precision agriculture, creating maps of agricultural soils, adequate methods of plant growth, and other issues of precision and conventional agriculture.","PeriodicalId":7527,"journal":{"name":"Agriculture (Pol'nohospodárstvo)","volume":"66 1","pages":"67 - 73"},"PeriodicalIF":0.0,"publicationDate":"2020-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87163082","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

They enter the soil and aquatic environment by atmospheric deposition, or by application of sewage sludge, pesticides, mineral and organic fertilisers, and by organic manures. Heavy metals (HMs) and risk elements can be determined in the soil by a wide range of analytical methods that differ in terms of time and financial costs, and the demands on service. One of the methods is the use of a portable XRF spectrometer under lab conditions, offering relatively fast determination of the concentration of chemical elements in the soil. In the presented study we evaluated the accuracy and the precision of the XRF device for analysis of the concentration of heavy metals (Pb, Zn, As, Mn, Cu, and Ni) in alluvial soils from the Mže and Otava river basins (Czech Republic), and validated and compared obtained results with the conventional lab method (ICP-OES). The soil samples (n = 502) were taken at 43 sampling sites at depths of 0 – 30, 30 – 60, and 60 – 90 cm, mainly in floodplains with Fluvisol soil type (N-year flow rates = Q100 m3/s). The multiple correlation coefficients R values ranged from 0.81 to 0.99. The R2 determination coefficients for individual HMs, measured by XRF, were determined as follows: Pb – 0.98, Zn – 0.97, Cu – 0.80, Mn – 0.79, As – 0.78, Ni – 0.66. According to our results, 66 – 98% points fit the designed models. The Pb and Zn have the best dependency (relationship tightness), and regression models are excellent. Cu, Mn, and As have a slightly worse dependency (tightness of the relationship), but the regression model is still very well suitable for agriculture practice, or for the purposes of environmental monitoring.","PeriodicalId":7527,"journal":{"name":"Agriculture (Pol'nohospodárstvo)","volume":"189 1","pages":"15 - 23"},"PeriodicalIF":0.0,"publicationDate":"2020-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76545584","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The insecticide Sumi-Alpha with active compound Esfenvalerate is widely used for cotton treatment in Uzbekistan. This insecticide is considered as moderately hazardous for different organisms of ecosystems, while more collected data and relevant research is a necessity for judgement of their safety and/or potential risk. Therefore, a comparative analysis of cotton leaves was performed to study the protein profile changes upon treatment with this insecticide. Our data showed elevated accumulation of fructose bisphosphate aldolase and degradation of RuBisCo in the treated tissue. Besides, a protein belonging to P-loop containing nucleoside triphosphate hydrolases superfamily exerted lower accumulation. Our results indicate that the applied pyrethroid pesticide possibly can affect photosynthesis performance and cause accumulation of simple saccharides which in turn might contribute to enhanced colonisation of sucking insects. Further molecular research on Sumi-Alpha effects on cotton is necessary for its safer use in agricultural practice.","PeriodicalId":7527,"journal":{"name":"Agriculture (Pol'nohospodárstvo)","volume":"41 1","pages":"40 - 44"},"PeriodicalIF":0.0,"publicationDate":"2020-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81015807","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, specific obstacles related to livestock manure composting in cold regions, such as the generation and preservation of temperature, and the solution of obstacles such as inoculation of coldadapted microorganisms, and the role of biochar in prolonging the thermophilic stage of composting were reviewed. Also, the challenges were adequately addressed, and promising strategies to improve composting of livestock manure under harsh conditions were proposed.

The study included 94- and 41-year-old experiments with mineral fertilisation (no fertilisation, NPK, CaNPK) and 25-year-old experiment with mineral fertilisation + farmyard manure (FYM) in 4-year cycle: FYM, FYM+NPK and FYM+CaNPK. The results show that in the 94-year-old experiment in NPK and CaNPK treatments, hydrolytic acidity (Ha) decreased in comparison with the control by 30% and 88%, respectively, while in 25- and 41-year-old experiments only the application of NPK significantly increased Ha values. The sum of basic cations increased by a factor of 10 at the most in the CaNPK treatment in the 94-year-old experiment. The same effect was also observed in the 25-year-old experiment. On the one hand, the sorption complex gradually became fully saturated as a result of fertilisation in the 94-year-old experiment. On the other hand, in the 25- and 41-year-old experiments, base saturation was substantially reduced.
